You may need an eyepiece sold
separately. The telescope does
not come with the eyepiece as
standard accessory unless you
purchased a package.
For the novice telescope user it is difficult to locate a selected object in the field of view at high
magnification. Using a finder scope will make this easier.

Magnification of the Telescope
When using an eyepiece with
short focal length (small number in
millimeters), the image will be dim
and the range of sharp focus will
be small. The image will be harder
to see so begin with an eyepiece
with long focal length. Dividing the
focal length of the telescope by
the focal length of the eyepiece
gives the magnification.
Example: Calculating the eyepiece magnification
of a telescope with 1035mm focal length (VMC110L).
